Liquid Settlement System

Description

Designed for remote measurement of settlement or heave in soils and man-made structures.

A vibrating wire pressure sensor is attached to a settlement plate located at the point of settlement. The sensor is connected via two liquid-filled tubes, extending laterally, to a reservoir located on stable ground. The sensor measures the hydraulic head of liquid between the sensor and reservoir locations. A vented cable runs from the sensor to a remote readout location.

Features:

Standard configuration includes one reservoir for each cell. Where settlements of two or more points long the same monitoring profile are of interest multi-position reservoirs are available

Also available as a Pneumatic Liquid Settlement Monitoring System. Similar to the VW system, but it uses a pneumatic pressure sensor. A reservoir is mounted at a higher elevation than the sensor in an area not subject to settlement
